Figure 5

Histograms displaying the heterogeneous frequency distribution of values of relative integrin alphavbeta3 immunofluorescence intensities from epithelial cells of primary breast cultures of normal tissue (A), and from epithelial cells of primary breast cancer cultures (B). The white bars represent the frequency of values derived from the marginal areas of the cells (termed as outer on the histogram), while the black bars represent the frequency of values derived from the main cell bodies (termed as inner on the histogram).
